Energy Transfer (EnT)-Mediated 2+2 Photocycloadditions

Puntos clave

• This research aims to explore the feasibility of [2+2] photocycloadditions of alkenes using energy transfer mediated by visible light.
• Utilized triplet energy transfer to effectuate cycloadditions under visible light conditions.
• Compared traditional UV irradiation methods with visible light approaches.
• Achieved successful [2+2] photocycloadditions without the need for high-energy UV irradiation.
• Demonstrated milder reaction conditions with better control over product formation.
